llVl PROVEIVI ENT IN SIRUP-VALVES.

Specification forming part of Letters Patent No. 416,938, dated March :21, 1865.

To all whom it may concern:

Be it known that I, A. D. PUFFER, of Somerville, county of Middlesex, State of Massachusetts, haveinvented an Improved Sirup-Valve; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention, sufcient to enable those skilled in the a-rt to practice it.

In that variety of beverage-fountains now in common use which employ a marble or other suitable casing for containing sirup vessels, ice, Ste., considerable difficulty has been experienced in securing the draft-valves thereunto. To remedy this difficulty, and to facilitate the fixture of such valves and similar articles, is one oi' the objects of my invention. In such fountains, and with measuring` discharge-valves employed to deliver a given quantity ot' sirup or other fluid, it is desirable, it' not absolutely necessary, to have air passages connected with the measuring-chambers, said-passages or pipes terminating` on higher levels than the surface-levels of the iuids to be drawn, the air-pipes being for the purpose of facilitating the emptying ofthe measuringchambers. 'Io hide said pipes from sight, to protect them, and avoid any necessity for making separate holes through the fountaincase for ingress and egress of said air-pipes, is another object of my invention.

Heretofore in securing a draft-valve to a fountain-case, and a Sirup or other receptacle within, it has been customary to project through the receptacle and case a hollow screw-plug, ,with a shoulder, l), against which, and between it and the receptacle, was a rubber or leather packing, c. The valve was then screwed upon the piece c, this being kept from turning, and the valve bein g turned around on a till it could be turned no more, by reason of the end of the valve case binding against the washer d, and in this condition the valve very seldom came in the right position, and had to be turned back, which left it loose and liable to leakage in the joint between a and the valvebody, and also left a looseness between the Sirup-case and the shoulder b and packing c.

Now, one part of my invention consists in supplyin g the end ofthe valve-case with an adjustable screw-collar, e, by which the hollow screw-plug ct is packed, and the valve is irml y held to the casing in its proper position.

By inspection of the drawing it will be readily seen that the valve-case can be turned upon the hollow screw-plug (t until it is perfectly tight and secure thereupon, the valvecase being all the time free to be left in the desired position, and that then when so placed rotation of the collar e in the proper direction will push the valve-case outward, confining it rigidly in position, and will draw the shoulder b hard against the packing c. The air-pipef is seen as passing' through or as contained within that part of the valve-case which leads directly from the Sirup-can, and as debouching into the nieasuring-chamber ofthe valve. The pipefis jointedwithin the sirupcan, and extends upward within it above the highest level ofthe sirup.

Itis unnecessaryto explain the construction ot' other parts of the valve, as they are not herein claimed as parts of my invention, and as they are clearly shown in lthe drawing.

1. The shouldered hollow screw-plug with its packing, the washer d, the screw-collar '6, and the screw-thread on the valve-case body, when arranged with a Sirup valve or faucet, substantially as shown and specified.

2. Conducting the air-tube, which facilitates the emptying ofthe measuring-chamber through the passage of the valve-case, substantially as and for the purpose described.
